Antenna (or aerial) represents a transducer for transferring or receiving electromagnetic waves. GSM antennas are created in two types: omnidirectional and directional antennas, and are designed to be applied in places where there is no connection with the mobile operator.
The application of high gain GSM antennas permits to improve the connection quality and the speed of data transfer via EDGE (Enhanced Data rates for GSM Evolution) and GPRS (General Packet Radio Service). Apart from improved performance and the opportunity to apply the mobile communication out of the mobile covering, cell phone antennas are known to reduce the backward radiation to the user. It's essential, since the electromagnetic wave power absorption is minimized and the performance of the antenna is increased. This way, the usage of cell phone antennas ensures high level of efficiency and health protection.
The purpose of cell phone antennas is to convert power between a circuit and the air, that's the reason why the effectiveness of the device depends on its input and radiation characteristics. Choosing an antenna is an important step, so we would advise to consult the professionals. Experts of the firm you are purchasing the antenna from will help you in making the right choice. But don't forget a number of important factors when choosing a cell antenna:
- Power should be supplied to the antenna with no being reflected back to the circuit. It signifies that the feeding point should supply the power, but not take it back;
- The power transferred to the antenna is transformed into radio waves;
- In case of any problems with the impedance, power should not be supplied to the antenna;
- Take into account that if the antenna is made of high loss materials, such as conductors and dielectrics, the supplied power will be lost due to transformation into the heat.
As far as you understand, high gain cellular antennas represent a wonderful choice in case you need a stable connection and high-speed data transmission. Besides, the usage of cellular antennas decreased the level of electromagnetic wave power absorption and in this way tells positively upon your health.
